Tuberculosis (TB) is an infection caused by slow-growing bacteria that grow best in areas of the body that have lots of blood and oxygen. That's why it is most often found in the lungs. This is called pulmonary TB. But TB can also spread to other parts of the body, which is called extrapulmonary TB.uberculosis (TB) is an infection caused by slow-growing bacteria that grow best in areas of the body that have lots of blood and oxygen.

A technical preview of the OS is already available, with the final version expected to reach handsets later this year. Some handsets, but not all, running Windows Phone 8.1 will be upgraded to Windows 10. At the show Microsoft announced a new smartphone, the Lumia 640XL, which it demonstrated running Windows 10 Technical Preview at its booth. It will ship with Windows Phone 8.1, but can be upgraded to Windows Phone 10.
Actually it's July 29th for the PC. Windows 10 Phone will come out later. Probably in the fall. Yes windows 8.1 phones will be able to upgrade to Windows 10 but some features like Continuum will require new Windows 10 devices.
